AC Energy Meter - 3Channel (Model: G-AC-M3P)
The G-AC-M3P is a compact, 3-channel AC energy meter for monitoring power consumption across three lines. It uses Hall-effect current sensing over a wide 4A–200A range at 11mV/A sensitivity, runs on 48VDC with 4000V isolation, and communicates over RS-485. Its ABS housing (under 130×140×60mm) clamps onto poles up to 150mm and mounts on walls or poles, with all connections on the front for easy installation. It's built for reliable, low-maintenance field use — stable calibration means no periodic recalibration.
Key Features
- 3-channel wide-range sensing - monitors 3 lines simultaneously, 4A-200A at 11mV/A sensitivity.
- External scrolling readout - read all parameters (3× Voltage, 3× Current, Power Factor, 3× kW, kWh) from outside without opening the box.
- Fault & tamper detection - detects disconnection/cable cutting of all Hall and voltage sensors, plus meter/box opening alerts.
- Isolated communication & sensing - RS-485 with isolated voltage/current sensing to cancel noise, interference, and protect the controller from spikes.
- Auto-cut protection - automatically disconnects on high voltage and reconnects when power normalizes.
- Maintenance-free calibration - stays accurate with no periodic recalibration, even if Hall sensor positions change.
